Product Description:
The Bürkert Type 6281 is a high-performance solenoid diaphragm valve designed with servo assistance, available in sizes up to DN 50. Utilizing a servo-assisted mechanism, this valve requires only a minimal differential pressure to operate effectively. This feature allows it to manage large flow rates while maintaining a compact design and energy-efficient coil system.
Constructed with versatile materials, the valve body can be chosen in standard brass that complies with European drinking water standards, dezincification-resistant brass, or stainless steel. These options ensure compatibility with a wide range of media and adherence to various international market requirements.
Equipped with integrated energy-saving "Kick and Drop" electronics featuring double coil technology, the Type 6281 guarantees reliable valve opening. At the same time, it significantly lowers power consumption during operation. Additionally, its vibration-resistant structure, smooth and quiet closing mechanism, and optional manual override make it a dependable choice.
Overall, the Bürkert Type 6281 is ideally suited for industrial automation applications where efficiency, reliability, and long service life are essential criteria.
Features:
Servo-Assisted Operation
This system utilizes line pressure to actuate the diaphragm, enabling dependable control of large flow rates, up to DN 50, through a compact solenoid design.
Energy-Saving Double Coil Technology
The "Kick and Drop" (KD) model employs a high-power pulse for positive valve opening, followed by a low-power hold mode. This approach significantly reduces energy consumption while ensuring the coil operates at a cooler temperature.
Robust & Quiet Design
Vibration-Resistant Coil
Featuring a centrally screwed coil system, this design guarantees a secure electrical connection and offers excellent resistance to both vibration and shock.
Damped Closing
An optimized pilot circuit coupled with a damping mechanism ensures that the valve closes softly and silently, effectively minimizing water hammer effects and reducing operational noise.
Versatile Materials & Certifications
The valves are available in multiple body materials, including Brass and Stainless Steel. The standard brass components meet European drinking water standards.
Additionally, explosion-proof variants certified with ATEX and IECEx are offered for safe operation in hazardous environments.
Easy Maintenance & Commissioning
An optional manual override feature provides simple testing, maintenance, or emergency operation capabilities in the event of power failure.
Long Service Life
A broad selection of diaphragm materials, such as NBR, EPDM, and FKM, ensures compatibility with various media while maintaining durable sealing performance over time.

Support and Services:
Burkert solenoid valves are precision-engineered components designed for reliable and efficient fluid control in various industrial applications. To ensure optimal performance and longevity of your Burkert solenoid valve, it is important to follow proper installation, operation, and maintenance guidelines.
Installation: Before installation, verify that the solenoid valve specifications match your system requirements including voltage, pressure, and media compatibility. Ensure the valve is installed in the correct flow direction as indicated by the arrow on the valve body. Use appropriate sealing materials and avoid excessive torque on fittings to prevent damage.
Operation: Operate the valve within the specified electrical and mechanical limits. Avoid rapid cycling and ensure that the valve is not exposed to pressures or temperatures exceeding its rated capacity. If the valve is used in a critical application, consider implementing safety measures such as pressure relief or monitoring systems.
Maintenance: Regular maintenance is essential for reliable operation. Periodically inspect the valve for signs of wear, corrosion, or damage. Clean the valve components to remove any deposits or debris that could impair function. Replace seals, diaphragms, or coils as needed according to the manufacturer's recommendations. Ensure electrical connections are secure and free from corrosion.
Troubleshooting: Common issues include valve failure to open or close, leakage, or coil burnout. Check for electrical supply issues, coil continuity, and proper voltage. Inspect the valve internals for blockages or mechanical damage. Refer to the product manual for detailed troubleshooting steps and corrective actions.
